The word “velleity” is a summation of the idiom “I couldn’t care less” — it means you have only the slightest inclination or the least possible level of motivation to do something. If you have velleity to do a chore, it won’t take very much convincing to get you to skip it. It comes from the Latin “velle,” meaning “to want, will,” and the combining form “-ity,” which indicates degrees of a condition.
